Figure 3 Comparison of DNase I with Alba. The N-terminal domain,
residues 1−86, of DNase I is coloured magenta, in complex with
a nicked DNA octamer (PDB code 2DNJ), and showing the  -hairpin
that interacts with the DNA minor groove. An Alba monomer is
superimposed in yellow, revealing the more extensive -hairpin
of Alba, and suggesting that the orientation of the DNA will be
different in the Alba−DNA complex. The phosphorus atoms of the
DNA are coloured green, and the side-chains of lysines 16 and 17
of Alba are shown.
